I just found out, new metro may use vesc hardware, from vesc project forum. But since Duty cycle mode is not well supported, (brake is not as strong as current mode, no regen)
it’s deal breaker for them apparently.
I used hobby esc, I like the duty mode for controlling speed, but the brake is really weak. tho there is a trick
Have anyone used Duty on VESC? Are they that bad?
